Investigation of the Corrosion Process of Concrete Pavement Tiles

UDC 620.193





Protection of concrete and reinforced concrete structures against corrosion is an important and urgent problem, the solution of which is aimed at increasing the service life of structures and structures of various purposes. The purpose of this article is to study corrosion of concrete paving tiles as a result of the effect on it of an aggressive aquatic environment. The solution of alkali (NaOH) (Type I corrosion) was selected as the aggressive component and was replaced periodically (after 2, 7 and 14 days). The results of the investigation of the corrosion process Type I of paving tiles allowed to determine the main kinetic dependencies of corrosion processes and corrosion rate. Based on the obtained dependencies, it is determined that the diffusion kinetic corrosion area for concrete paving tiles occurs after 7 days. After 14 days, there will be a diffusion corrosion area. The fracture depth of the pavement concrete at the time of the end of the test (0.017 cm) and the predicted fracture depth for the life of the product (0.18 cm) have been calculated. As a result of experimental studies, it has been determined that the quality assessment of the product can be carried out not only on physical and mechanical properties, but also on durability and anti-corrosion properties. The appropriateness of different protection measures, the variation of components of the mixture composition in the manufacture of tiles and their effectiveness can be assessed by comparing the corrosion rate and the fracture depth of protected and unprotected concrete.
